Leadership in times of change

I saw an article about leadership and what is required in times of change. It was fascinating to read as several experts outlined the requirements. My first thought was yea so – we are always in times of change if you are leading there is no such thing as the status quo and going back to what was is not an option. Then I read this most recent shocking finding (see below). I wonder or perhaps I am wandering when we as leaders will choose to begin to do what is right for children whether that be mass customizing or simply expanding recess as this certainly non-scientific study suggests http://www.scarymommy.com/texas-school-triples-recess-time-and-sees-immediate-positive-results-in-kids/
